The V4073A Mid-position Diverter Valve must be positioned where it cannot block any vent or cold feed when either port A or B are closed
It may be plumbed in at any angle but the flow must go into Port AB and must not be mounted so that the powerhead is below the horizontal level of the pipework
If fitted in a confined space, sufficient ventilation must be available to keep the valve within its ambient temperature range and access must be provided to remove the powerhead if necessary
28mm Compression connections
Spring return action
Powerhead replaceable without draining down
Manual lever for filling and draining down
Quiet operation with minimal power consumption
1m flying lead, head resistant cable requiring a 230V AC power supply
